Moxa NPort 5232 2-port RS-422/485 serial device servers
Introduction
Moxa NPort 5232 serial device servers are designed to make your industrial serial devices Internet-ready in no time. The compact size of NPort 5232 serial device servers makes them the ideal choice for connecting your RS-422/485 serial devices-such as PLCs, meters, and sensors-to an IP-based Ethernet LAN, making it possible for your software to access serial devices from anywhere over a local LAN or the Internet. The NPort 5200 Series has a number of useful features, including standard TCP/IP protocols and choice of operation modes, Real COM/TTY drivers for existing software, and remote control of serial devices with TCP/IP or traditional COM/TTY Port.
Standard TCP/IP Protocols and Choice of Operation Modes
Moxa NPort 5232 device servers can operate in TCP Server, TCP Client, or UDP operation mode, ensuring compatibility with software based on a standard network API (Winsock, BSD Sockets).
Real COM/TTY Drivers for Existing Software
With the Real COM/TTY drivers that are provided with each NPort, software designed for communication with COM/TTY ports can be instantly and seamlessly integrated into a TCP/IP network. This is an excellent no fuss way to preserve your software investment and enjoy the benefits of networking your serial devices.
Control Remote Serial Devices with TCP/IP or Traditional COM/TTY Port
By specifying the NPort 5232's IP address and port number, a network sockets API can obtain access to the attached serial device over the network, from any host computer that supports TCP/IP. For legacy Windows or Linux software that is COM or TTY-based, Moxa's COM/TTY drivers provide a seamless way of operating over the network.
Features and Benefits
- Compact design for easy installation
- Socket modes: TCP server, TCP client, UDP
- Easy-to-use Windows utility for configuring multiple device servers
- ADDC (Automatic Data Direction Control) for 2-wire and 4-wire RS-485
- SNMP MIB-II for network management
